iPhone5 stolen by Sheridan Court Apartments, Dorset St Upper

On Friday, Sept 1, my phone was snatched from my hands. The guy was wearing a grey hoodie sweater so I couldn't see him clearly. He ran into the alley into the Sheridan Court Apartments and disappeared. With only one way out, I believe he may live there. He wasn't expecting me to follow. Phone is a black iPhone5 with a cracked camera on the back. It had a black battery case. It's not worth very much so I'm assuming he'll toss it or try to sell it cheap. It had a lot of photos I never backed up and hope someone will find it.
